Most tools are either part of the Dyalog interpreter or included with the Dyalog installation image. All tools that are written in APL are supplied with source code. A growing number of tools, as well as code samples showing how to use the tools, are being made available as open-source projects via a GitHub repository.

Separately-Licensed Tools

As described above, a number of tools are licensed and bundled with Dyalog, including everything you need to write applications on most platforms. We also embed some open-source tools such as the PCRE engine for regular expression handling and GNUTLS for secure communications.

Most of the tools are available to any user of Dyalog – including users of non-commercial or free licences. However, a small number of tools are sold separately due to third-party licensing or a requirement for high availability service levels.
